NOZZLE FOR HOSE-PIPES.

SPEGTFIGATION forming part of Letters Patent No. 2'78,008, dated May 22,1883.

Application filed March 14, 1883.

To all whom it may concern:

Be it known that I, 'ljHoMAs HALEY, a citizen of the United States,residing at Cambridge, in the county of Middlesex and State ofMassachusetts, have invented certain Improvements in GontrollingorShut-Off Nozzles for Hose-Pipes, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, making part of this specification, in which- Figure 1 is anelevation of my improved controlling-nozzle forhose-pipes. Fig. 2 is avertical section through the center of the same. Fig. 3 is a horizontalsection on the line or m of Fig. 2, the position'of theparts beingchanged Figs. 4, 5, 6, 7, and 8,'.detailsin perspective.

My invention relates to certain improvements on the controlling-nozzlefor hose-pipes for which Letters Patent of the United States No. 177,239were granted to me May 9, 1876.

, The construction of the nozzle described in the aforesaid LettersPatent did not admit of the stream being entirely shut off, but onlyenabled the diameter of the stream to be changed, and my presentinvention has for its object to enable the stream to be entirely shutoff when required, as hereinafter described.

My invention also has for its object to render the sliding blocks orgates which shut off or control the stream perfectly water-tight whenclosed together, and take up any wearthatwouldoccasionleakageatthispoint; audit consistsin the combination,with the cap, of an adjustable bushing screwed into the cap in front ofthe sliding blocks or gates and adapted to be turned by a wrench orother suitable implementto cause its inner end to take a'firm bearin gagainst the sliding blocks when closed together, and thus take up wearand maintain a tight joint, whereby all leakage is prevented at thispoint.

My invention also consists in certain details of construction, ashereinafter more fully set forth, whereby leakage between the cap andthread, a, over which fits a corresponding screw-thread on the interiorof a movable sleeve,

(No model.)

B, the upper enlarged end of which is bored out, forming a shoulder, I),upon which rests a leather washer or packing-rill g, 0, over which fitsa flange, d, on the under side of a ring, D, which is firmly screwedonto the upper end of the portion 10 of the nozzle A, so as to bestationary thereon, the enlarged end of the sleeve B being adapted toturn on the flange d. 1 The ring D is provided on its upper surface.

on each side of its aperture 0, with a segmental through the hose-pipeto entirely shut off the stream of water as required. These blocks 9 gare provided with pins h h, which project into cam-grooves it, formed inthe under side of a cap, E, which is provided on its interior with ascrew-thread, k, which fits over a corresponding screw-thread on theoutside of the upper enlarged end of the sleeve B, and by thus screwingtogether the cap E and the sleeve B, instead of making a smooth jointand securing these parts together by a series of screws, as describedand shown in my aforesaid Letters Patent of May 9, 1876, a much tighterjoint can beformed at this point with less labor, and liability ofleakage thus avoided, while the operation of puttin g together thenozzle and takin g it apart is greatly facilitated.

Through the outer end of the cap E is formed a circular aperture, m, forthe passage of the water to the tip or outer end, a, of the nozzle,

from which it is discharged in a stream of the desired diameter. The tipa is made removable, so that it can be taken off and replaced by anotherhaving an orifice of different diameter, and is preferably of a littleless interior diameter than that of the lower portion of the nozzle, inorder to condense and solidify the stream.

The outside of the cap E is fluted, as seen at p, to facilitate itsbeing turned by the hand, and when the parts are in the position seen inFig. 2 and it is desired -to shut off the stream, as is often required,it is simply necessary to turn the cap E by hand a quarter of arevolution, which causes the cam-grooves t i to act on the pins h h andbring the blocks or gates together, thus instantly arresting the passageof the water, a quarter-revolution in the opposite direction againopening the gates to their full extent and letting n the stream, and byturning the cap E more or less to increase or diminish the distancebetween the edg'es 12 of the gates g the force of the stream and thedistance to which the water is projected may be augmented or reduced, asdesired. When the cap E is turned to shut 0d the water, the blocks g, asthey ELI'Q'ClOSGd together, are brought down upon the upper end of themain portion A of the nozzle, the surfaces of the parts in contact beingground to prevent the escape of water laterally into the cap.

The aperture m at the outer end of the cap E is provided with ascrew-thread, g, for the reception of a corresponding thread on the out-'side of an adjustable bushing, G, which is screwed into the aperture muntil its inner end projects slightly beyond the inner face of the capE, so that when the latter is turned to close the sliding gates gtogether the upper surfaces of the latter are brought firmlyinto contactwith the projecting end of thebushing G, thus forming a perfectlywater-tightjoint and preventing all leakage and cousequentdamageresulting therefrom; and it will be apparent that any wear of the end ofthe bushing or the surfaces of the gates can be taken up or compensatedfor by simply screwing in the bushing by means of a wrench having pinsadapted to enter the-apertures r in its outer end, which is readilyaccessible when the tip a is removed, the employment of this adjustablebushing rendering it easy to maintain a ti ht joint, which wouldotherwisebe difficult, owing to the y necessity of bringingtheinner endsof the camgrooves i as close as possible tothe edge of the aperture m,to avoid making the cap E of larger diameter than is absolutelynecessary.

I What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, with the nozzle A, of the movable sleeve B, the-ringD, with its guideways, the sliding blocks or gates g g, having squareends 12, and adapted, when closed together, to entirely shut off thewater, the pins h h on the gates, and the cap E, with its cam-grooves i43, all constructed and arranged to operate substantially in the mannerand for the purpose set forth.

2. In a controlling-nozzle for hose-pipes, the combination, with the capE and the sliding blocks or gates g g, operating as described, of anadjustable bushing, G, screwed into the cap in front of the slidinggates, and adapted to bear thereon at its inner end, substantially inthe manner and for the purpose set forth.

8. In a controlling-nozzle for hose-pipes, the combination of the nozzleA, the movable sleeve 13, with its shoulder band washer 0, the ring 1),with its sliding gates g 9, provided with pins h h, and the cap 'E, withits camgrooves t i, and having on its interior a thread, 70, to adapt itto be screwed onto the upper end of the sleeve B, all constructed andarranged to operate substantially as and for the purpose described.

Witness my hand this 9th day of March, A. D. 1883;

THOMAS HALEY.
